Abstract

A liquid analysis container includes a main body and a barrier device. The main body has an accommodating space and a first opening. The barrier device is disposed on the main body and covers the first opening. An accommodating cavity is formed between the barrier device and the main body. The accommodating cavity is connected to the accommodating space through the first opening. The barrier device has a second opening. The accommodating cavity is connected to an external environment through the second opening. An opening diameter of the second opening is larger than an opening diameter of the first opening.

Claims

1. A liquid analysis container, comprising:

a main body including an accommodating space and a first opening; and

a barrier device disposed on the main body and covering the first opening, wherein an accommodating cavity is formed between the barrier device and the main body, the accommodating cavity is connected to the accommodating space through the first opening, the barrier device has a second opening, the accommodating cavity is connected to an external environment through the second opening, and an opening diameter of the second opening is larger than an opening diameter of the first opening.

2. The liquid analysis container of claim 1, wherein a dropper is adapted to be inserted into the accommodating space through the second opening and the first opening and injects an under-testing liquid into the accommodating space, and the under-testing liquid remaining around the first opening is limited within the accommodating cavity by the barrier device.

3. The liquid analysis container of claim 2, wherein when the dropper is inserted into the accommodating space, there is a gap between the dropper and an inner edge of the second opening.

4. The liquid analysis container of claim 1, wherein the first opening is located in an orthographic projection of the second opening on the main body.

5. The liquid analysis container of claim 1, wherein an inner diameter of the accommodating cavity is larger than the opening diameter of the second opening.

6. The liquid analysis container of claim 1, wherein the main body further has a third opening covered by the barrier device, the accommodating cavity is connected to the accommodating space through the third opening, and the under-testing liquid in the accommodating cavity flows to the accommodating space through the third opening.

7. The liquid analysis container of claim 1, wherein the accommodating space is partitioned into a first subspace and a second subspace, the first subspace is connected to the accommodating cavity through the first opening, the main body further has a third opening covered by the barrier device, the second subspace is connected to the accommodating cavity through the third opening, and the under-testing liquid in the accommodating cavity flows to the second subspace through the third opening.

8. The liquid analysis container of claim 1, wherein the main body further has a channel and a chamber, the chamber is connected to the accommodating space through the channel, the chamber is adapted to contain an agent, and the under-testing liquid is adapted to flows to the chamber through the channel.

9. The liquid analysis container of claim 1, wherein the barrier device comprises:

an annular body disposed on the main body and surrounding the first opening; and

a cover covering the annular body, wherein the second opening is formed on the cover, and the accommodating cavity is formed among the cover, the annular body, and the main body.

10. The liquid analysis container of claim 1, wherein a surface of the main body has a concave, and the first opening is formed at a bottom of the concave, and the barrier device is embedded in the concave.
